HENRY G. SEIPP, OF OORAOPOLIS, PENNSYLVANIA.

PAVEMENT OR VAULT CONSTRUCTION.

To all whom it may concern:

Be it known that I, HENRY C. Snirr, a resident of Coraopolis, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Pavement or Vault Construction; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to pavement or vault construction, and has special reference to such constructions which are commonly known as pavement or sidewalk lights.

The object of my invention is to provide for a cheap, simple and efficient construction of a sidewalk light, which will not only do away with the false work usually employed in this class of work, but will enable it to be formed rapidly, cheaply and conveniently, and will allow for the easy and quick placing and removal of the supporting or mold section and for its use at other places.

My invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved construction of pavement or sidewalk lights, I will describe the same more fully, referring to the accompanying drawing, in which Figure 1 is a top plan view of a sidewalk light employing my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a like view with the molding plate removed and showing the completed light. Fig. 4: is a top plan view of another form of the light. Fig. 5 is a longitudinal vertical section of the same. Fig. 6 is a like view showing a modification of the invention. Figs. 7 and 8 are detail views showing other forms of the invention.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing 1 represents the reinforcing or supporting bars which -are of the usual T-shape construction and are arranged at predetermined distances apart and parallel with one another. The ends of the bars 1 are supported in the usual or well known manner, and connected to the flange 2 on said bars are the clips 3, which are preferably formed of wire and bent to shape to Specification of Letters Patent.

form the hooked-shaped portions 4 at their ends and the eye portion 5 centrally of the same for extending under said flange. These clips 3 are placed along the bars 1 and are adapted to fit loosely on the flange 2 of said bars, so that they can be slid along said flange and placed at suitable distances apart from each other, as hereinafter described.

Fitting under the bars 1 and clips 3 is the molding or supporting plate 6 which is preferably formed of metal and is provided with a series of slots 7 through the same in rows and at suitable distances apart. This plate 6 is also provided with a series of centers 8 having inclined sides 8, which centers are secured to the upper or inner surface of the plate by means of a bolt or rivet S) passing through the same, and are usually placed in rows and at equal and suitable distances apart. The plate 6 is placed in position under the bars 1 and while being held in any suitable manner in such position the eye portions 5 on each of the clips 3 are placed through the slats 7 in said plate and a pin 10 run or driven into the eye 11 of said portions 5 so that it bears against the outer face of said plate and said eye portion to hold the plate in position. After the plate 6 is thus held in position the hollow glass tiles or prisms 12 are each placed in position around each of the centers 8 by the inclined inner walls 12 of the hollow por tion in said prisms being guided along and held against the inclined sides 8 on said centers, and after the prisms are in position the cement or concrete 13 is then filled in against said plate and around the bars 1, clips 3 and prisms 12 in the usual and well known manner. When the cement or concrete 13 has become sufficiently set the pins 10 are removed from the eyes 11 in the eye portions 5 of the clips 3 and then the plate 6 with its centers 8 is removed or taken down from the work, so leaving the pavement or sidewalk light completed. After the pavement or sidewalk light is thus completed it can be further finished, if desired, by cutting or clipping off the portions of the eye portions 5 on the clips 3 extending through the concrete 13 by any suitable instrument in order to leave a smooth finish to the interior surface of said light, although such portions 5 can serve as hangers in the work when projecting through the concrete to suspend articles therefrom.

If desired, a corrugated strip 14: can be placed on each side of the bars 1 and such strip provided with holes or openings '15 through the same, so that the cement or concrete 13 will fill in, through and around the strip when placed in the work, as shown in Figs. 4 and 5, in order to form a stronger of the other ends, as at 16, can extend through a hole 17 in the plate 6 and be threaded, so that a nut 18 can engage with said threaded end and bear against the plate to hold said plate in place. In removin the plate 6, the nuts 18 can be unscrewed from the threaded end 16 of the clips 3, so that the said plate can be taken away, thereby leaving the completed light, and if desired, the said ends 16 projecting through the concrete 13 can be cut or clipped off in any suitable manner to leave the more finished and, smooth interior surface for the light. This form of construction is also substantially shown in Figs. 7 and 8 and both forms showing a bolt 19 projecting through the plate 6 and attached thereto in the manner indicated. In the former figure the hook portion 5 is done away with and the bolt passes through a hole in the flange of the bar so that the head on said bolt can rest against the flange, while in the latter figure the bolt is extended up through a like hole in the flange, and has a hook portion 20 fitting over the top edge of the bar or a form of such hook can be made in a shorter bolt to pass through a hole in said bar, as shown in dotted lines in said figure. It will thus be seen that my improved pavement or sidewalk construction will enable the work of building the same to be performed in such a manner as to permit the use of a supporting means to act as a mold or former for,

such work, and such means can be used continuously in this work and for different kinds of constructions. that my improved manner of forming this construction can be applied to vaults, areaways, skylight constructions and other constructions of the same general character.

Obviously, the hereindescribed improve It will also be seen What I claim as my invention and desire to secure by Letters Patent, 1s
